JAMES A. MCNAMARA, OF NEW YORK, N. Y.

UMBRELLA.

a citizen of the United States, and residing in the Bronx, in the cityand county of New York and State of New York, have invented certain newand useful Improvements in Umbrellas, of which the following is aspecification, such as will enable those skilled in the art to which itappertains to make and use the same.

This invention relates to umbrellas, parasols and like devices, and theobject thereof is to provide an improved device of this classparticularly designed for use as an umbrella and which may be compactlyfolded or closed up and shortened so that it may be packed in a smallspace and conveniently carried in a hand bag, trunk, or like receptacleand which will also be strong and durable, and the frame work of whichwill not be apt to get out of order or need repair.

The invention is fully disclosed in the following specification of whichthe accompanying drawing forms a part, in which the separate parts of myinvention are designated by suitable reference characters in each of theviews, and in which Figure l is a view showing my umbrella compactlyfolded together in its smallest form Fig. 2 a view showing the umbrellafolded but ready for expansion and use Fig. 3 a side view of the framework of my improved umbrella and showing only onehalf thereof andshowing the ribs extended. Fig. i a view similar to Fig. 3 but on anenlarged scale and showing only two of the ribs and corresponding braceswith parts in section; Fig. 5 a view on an enlarged scale with the coverdetached and showing the parts of the frame folded together, as shown inFig. 1 Fig. 6 a section on the line 66 of Fig. 4c and on an enlargedscale, and Fig. 7 a view showing a detail construction in section.

In the practice of my invention I provide an umbrella frame comprising astick a, ribs 5 and two sets of braces 0 and (Z mounted on and movableon the stick a, said parts being constructed and operating ashereinafter described. The stick a is provided with a head 6 with whichthe ribs 5 are connected, and the ferrule end a of the stick isdetachably connected with said head. Mounted on the stick a is a sleevef provided at its lower end with a head f Specification of LettersPatent.

and mounted on the. sleeve 7 is a supplemental sleeve g. The braces 0are connected with the upper or inner end of the sleeve f at c", andwith the ribs Z) at 0 and the braces (Z are connected with the lower endof the supplemental sleeve g, and with the ribs 2') at 0 or the pointwhere the braces c are connected therewith.

The ribs 7) are composed of separate tele scopic parts 6 and b the outerparts 5 being tubular in form and the inner parts 6 being adapted toslide therein, and mounted on the parts 25 are spiral springs 72, theouter ends of which are secured to the inner ends of the parts 5 of theribs at 7L2, and the inner ends of which are contracted or tapered so asto closely grip the parts 6 of said ribs and at the same time permitthem to slide freely thereon.

Mounted on the sleeve f is a spiral spring 2' which also incloses thesleeve 9 and which has a bearing at the upper or inner end 9 of saidsleeve f where the braces 0 are connected therewith, and at its lowerend said spring has a bearing on the head g of the sleeve 9 with whichthe braces d are connected.

The stick a is divided at a into saparate parts and the lower or outerpart a with which the handle 70 is connected is provided with a threadedshank a adapted to be screwed into the corresponding end of the otherpart which is similarly threaded.

The head f of the sleeve f operates in connection with the usual springcatch on mounted in the stick a, and pivoted to said stick adjacent tothe handle 70 is a hook j adapted to engage an eye j on the head f tohold the cover, ribs and brackets in the approximate position shown inFig. 2, when desired.

In the position of the parts shown in Fig. 2, the cover, ribs and bracesare not com pactly folded on the stick, and the braces (Z with thesleeve 9 do not show in said figure.

The cover, ribs and braces are expanded for use, as shown in Figs. 3 and4, in the same manner as other umbrellas, and said parts are foldedtogether as shown in Figs. 2 and 5 in the same manner, and in thisoperation the parts 6 of the ribs I) slide freely on the parts 6 and thesleeves f and 5 slide freely on the stick, and the upward or outwardmovement of the braces 0, in the operation of expanding the umbrella foruse, is limited-by a stop n in the stick a.

The ribs and braces do not assume the position shown in Fig. 5 by simplyfolding the same with the cover, as shown in Fig. 2, but when said partsare folded, as shown in said figure, if the stick or handle be graspedin one hand and the other passed down over the body of the umbrella to apoint indicated by the dotted line as in Fig. 2, the ribs, braces andcover may he slid together, as shown in Figs. 1 and 5 by pulling thestick outwardly, or by moving the cover and ribs in the oppositedirection While the stick is held stationary.

When the handle end portion of the stick has been detached, the ferruleend a may be screwed into the socket left vacant by the shank a of thehandle end portion a of the stick, and the handle end portion of thestick may be inserted into the folded parts, as shown in Fig. 1, but theferrule end portion a of the stick need not necessarily be connectedwith the handle end portion and is not so shown in Fig. 1

By providing the double set of brace-s as herein shown and described andconnecting the same with the stick by means of the sleeves f and g, asshown and described, the sleeve 9 being slidably mounted on the sleeve fand by making the ribs telescopic, I provide a strong and substantialframe which can be folded compactly together and which will operateeasily and freely in extending and folding the separate parts of theumbrella, and the springs it also facilitate said operation bypreventing the toofree movement of the parts 6 of the ribs on the partsb thereof and limiting and regulating such movement.

Having fully described my invention what nected with the 'loweror outerend of the last named sleeve and with the ribs, and a spiral springplaced on said sleeves between the separate sets of braces, said ribsbeing also provided with spiral springs which are wound on the inner endportions thereof and connected with the outer end portions thereof.

2. In an umbrella, a stick, ribs connected therewith and composed ofseparate telescopic parts, a sleeve mounted 011 the stick, asupplemental sleeve mounted on said first named sleeve, a set of bracesconnected with the top or inner end of the first named sleeve and withthe ribs, another set of braces connected with the lower or outer end ofthe last named sleeve and with the ribs, and a spiral spring placed onsaid sleeves and bearing on the separate sets of braces, said ribs beingalso provided with friction devices connected with one part thereof andoperating in connection with the other part.

In testimony that I claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this 25th day of April1913.
